RemoteContractNegotiable

Job Overview

A new opening is available for an API Solution Architect – Node.js. The role is remote and is classified as contract. The requirements point towards JavaScript, TypeScript, Node.js, Express.js, REST APIs, Artificial Intelligence and LLMs. The experience level listed is W2 / C2C. For general context: Node.js lets developers run JavaScript on the server. REST APIs let the front end and back end of an application exchange data in a structured way. Read the details below carefully and use the application link on this page if the role matches your profile.

Required Skills and Qualifications

★ 8+ years of software development experience with 3+ years in a Solution Architecture role.
★ High proficiency in Node.js, Express/NestJS, and JavaScript/TypeScript.
★ Deep hands-on experience with REST, GraphQL, gRPC, and WebSockets.
★ Strong knowledge of API security, rate-limiting, throttling, and caching strategies.
★ Expertise in Cloud Platforms (AWS, Azure, or GCP), Docker, Kubernetes, and CI/CD pipelines.

What These Requirements Mean in Practice

★ JavaScript: Typically means writing and debugging everyday JavaScript, including asynchronous code, array and object handling, and modern ES6+ syntax.
★ TypeScript: Adds types to JavaScript so mistakes are caught earlier; day to day it means defining interfaces and typing function inputs and outputs.
★ Node.js: Running JavaScript on the server to build APIs, handle requests and talk to databases.
★ Express.js: A minimal Node.js framework used to define routes and middleware for web servers and APIs.
★ REST APIs: Designing and consuming HTTP endpoints so a front end, mobile app or another service can exchange data.
★ GraphQL: Querying exactly the data a client needs through a single endpoint instead of many fixed ones.
★ Git and GitHub: Tracking changes, working on branches, opening pull requests and resolving conflicts so a team can share code safely.
★ Docker: Packaging an application and its dependencies into containers so it runs the same way everywhere.

Skills to Brush Up Before Applying

★ JavaScript: promises and async/await, array methods such as map, filter and reduce, closures and scope
★ TypeScript: interfaces versus type aliases, generics basics, typing API responses
★ Node.js: npm and modules, building a simple REST API, asynchronous file and network operations
★ Express.js: routing and middleware, error handling, request validation
★ REST APIs: HTTP methods and status codes, authentication basics such as tokens, validation and error responses
★ GraphQL: queries, mutations and schemas, resolvers, how it compares with REST
★ Git and GitHub: branching and merging, pull requests and code review, resolving merge conflicts
★ Docker: Dockerfile basics, images versus containers, docker compose

Who May Be a Good Fit for This Role?

This role may be suitable for candidates who bring substantial experience and are comfortable owning technical decisions and supporting other team members. Those who are comfortable with JavaScript, TypeScript, Node.js, Express.js, REST APIs, Artificial Intelligence and LLMs and enjoy building practical projects may find the requirements a good match. A remote arrangement may suit people who work well independently and communicate clearly in writing. This is editorial guidance only, and the employer makes the final decision on suitability.

Application Tips

Applicants may want to highlight relevant experience with JavaScript, TypeScript, Node.js and Express.js in their CV. Because version control is mentioned, a GitHub profile with a few well-described repositories can make your skills easier to verify. If you have used AI tools or built small projects with language models, briefly describe what you built and how you checked the results. Since applications are sent by email, use a clear subject line that includes the role title and keep your message short, with your CV attached. A short, role-specific summary at the top of your CV usually reads better than a generic profile. These are general tips, not requirements stated by the employer.

Prepare for Your Interview

These suggested questions can help you prepare for an interview by focusing on the skills, responsibilities, and technical areas relevant to this role. They are for preparation only and are not confirmed employer questions.

Q: How would you structure a Node.js project so that routes, business logic, and data access stay separate?
Q: What is middleware in Express, and how would you use it for authentication or error handling?
Q: How would you handle authentication and input validation for a REST API you are building?
Q: How does GraphQL differ from REST, and when would you prefer one over the other?
Q: How do closures, promises, and async/await work in JavaScript, and when would you use each?
Q: How do interfaces and type aliases differ, and when would you choose one over the other?
Q: How do you stay organised and communicate clearly when working remotely?
Q: Tell us about a technical decision you owned and how you handled the trade-offs.
Q: How do you review code and support less experienced teammates?
